Description

Technical Field

[0001] This utility model relates to the technical field of pin grooving, and in particular to a grooving device for pin processing. Background Technology

[0002] In the field of mechanical manufacturing and assembly, pins, as a widely used basic connecting component, often require grooves (such as sealing ring grooves) to be machined on their outer circumference to meet functional requirements such as installing sealing elements or transmitting torque. Currently, the grooving of pins still largely relies on manual loading and unloading, that is, operators manually clamp the workpiece onto the machining table, complete the grooving, and then manually unload and replace the part. To improve automation, some companies are trying to introduce robotic arms to perform loading and unloading operations.

[0003] However, both manual operation and robotic assistance employ a discrete work mode. Frequent manual intervention or the cyclical process of a robotic arm's single grab-and-place operation consumes a significant amount of non-cutting time, resulting in low equipment utilization and limiting overall grooving efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this utility model is to provide a grooving device for pin processing, which ensures the continuity and stability of the processing process by realizing automatic feeding of the pin, thereby significantly improving the overall efficiency of grooving operations.

[0006] To achieve the above objectives, the first aspect of this utility model provides a grooving device for processing pins, comprising a processing table, a rotary drum, a docking drum, a pushing component, and a grooving component. The processing table is provided with a support plate, the rotary drum is rotatably mounted on the support plate, and a pneumatic chuck is mounted on the rotary drum. The processing table is provided with a first slide module, the docking drum is mounted on the slide of the first slide module via a bracket, and the first slide module is located on the opposite side of the pneumatic chuck. A material box is connected to the docking drum. The pushing component is mounted on the docking drum. The processing table is provided with a transmission component, which is connected to the pushing component. The grooving component is mounted on the processing table and located on one side of the pin.

[0007] In addition, the grooving device for pin machining proposed in this utility model may also have the following additional technical features: Specifically, the pushing assembly includes a lead screw, a ball bearing slider, and a push plate. The docking cylinder is provided with a first connecting plate and a second connecting plate, and the lead screw is rotatably disposed between the first connecting plate and the second connecting plate. The push plate is slidably disposed inside the docking cylinder. The docking cylinder is provided with a sliding groove, and the ball bearing slider is threadedly connected to the lead screw, and the ball bearing slider passes through the sliding groove and is connected to the push plate.

[0008] Specifically, the transmission assembly includes a transmission shaft, two bevel gears, a circular gear, and a gear plate. The transmission shaft is rotatably mounted on the first connecting plate. The two bevel gears are respectively mounted on the lead screw and the transmission shaft, and are meshed with each other. The circular gear is mounted on the transmission shaft. The processing table is provided with a vertical plate, and the gear plate is mounted on the vertical plate and is meshed with the circular gear.

[0009] Specifically, the grooving assembly includes a second slide module, a tool holder, and a grooving tool, wherein the second slide module is disposed on the processing table; the tool holder is mounted on the slide of the second slide module; and the grooving tool is mounted on the tool holder.

[0010] Specifically, the inside of the rotating drum is equipped with a driving component, and the output end of the driving component is equipped with a feeding plate.

[0011] Compared with existing technologies, this invention has the following advantages: Automatic docking of the docking cylinder and the three-jaw chuck is achieved through the first sliding table module. With the cooperation of the transmission component, the pushing component pushes the pin into the chuck to complete automatic centering and loading. During the resetting of the docking cylinder, the grooving component performs processing simultaneously. After processing, the unloading plate pushes out the pin, and the pin to be processed in the hopper automatically falls into the docking cylinder, preparing for the next loading.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The grooving device for pin machining according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, the grooving device for pin processing according to this utility model embodiment includes a processing table 1, a rotating cylinder 2, a docking cylinder 3, a pushing component 4, and a grooving component 5.

[0018] The processing table 1 is equipped with a support plate 6, the rotating drum 2 is rotatably mounted on the support plate 6, and the rotating drum 2 is equipped with a pneumatic chuck 7.

[0019] It should be noted that the three jaws of the pneumatic chuck 7 can move synchronously toward or away from the center, thereby automatically positioning the pin at the center of the chuck. The specific structure and working principle of the pneumatic chuck 7 are existing technologies, and will not be described in detail here.

[0020] Furthermore, the rotating drum 2 is connected to an external drive motor, which is mounted on the support plate 6. The drive motor can drive the rotating drum 2 to rotate, thereby driving the pin shaft to rotate.

[0021] The processing table 1 is provided with a first slide module 10, and the docking cylinder 3 is set on the slide of the first slide module 10 by a bracket, and the first slide module 10 is located on the opposite side of the pneumatic chuck 7.

[0022] It should be noted that, see Figure 5 The docking cylinder 3 can just accommodate two pins arranged in front and behind, and the docking cylinder 3 is coaxially set with the rotating cylinder 2. The first slide module 10 can drive the docking cylinder 3 to move closer to or away from the rotating cylinder 2 to facilitate subsequent material loading.

[0023] A material box 8 is connected to the docking cylinder 3; a pushing component 4 is set on the docking cylinder 3; a transmission component 9 is set on the processing table 1, and the transmission component 9 is connected to the pushing component 4.

[0024] In an embodiment of this utility model, the material box 8 contains a plurality of pins, and the material box 8 has a channel that allows a single pin to pass through. The pin in the material box 8 passes through the channel and enters the interior of the docking cylinder 3.

[0025] Furthermore, when the first slide module 10 drives the docking cylinder 3 to move towards the rotating cylinder 2, the pushing component 4 is activated with the cooperation of the transmission component 9. The pushing component 4 can push the pin inside the docking cylinder 3 into the rotating cylinder 2, and center and position it through the pneumatic chuck 7, thus realizing the feeding of the pin.

[0026] The grooving assembly 5 is set on the processing table 1 and located on one side of the pin.

[0027] In an embodiment of this utility model, the grooving component 5 can groove the pin to meet the processing requirements of the pin.

[0028] In one embodiment of this utility model, such as Figure 3 As shown, the pushing assembly 4 includes a lead screw 41, a ball slider 42, and a push plate 43. The docking cylinder 3 is provided with a first connecting plate 11 and a second connecting plate 12, and the lead screw 41 is rotatably disposed between the first connecting plate 11 and the second connecting plate 12. The push plate 43 is slidably disposed inside the docking cylinder 3. The docking cylinder 3 is provided with a groove 31, and the ball slider 42 is threadedly connected to the lead screw 41, and the ball slider 42 passes through the groove 31 and is connected to the push plate 43.

[0029] It should be noted that the lead screw 41 is set parallel to the central axis of the docking cylinder 3, the slide groove 31 is set along the length of the docking cylinder 3, and the ball slider 42 is slidably connected to the slide groove 31. The slide groove 31 can guide the movement direction of the ball slider 42. When the lead screw 41 rotates, with the cooperation of the ball slider 42, it drives the push plate 43 to move, so as to push the pin inside the docking cylinder 3 into the pneumatic chuck 7.

[0030] Furthermore, such as Figure 3 As shown, the transmission assembly 9 includes a transmission shaft 91, two bevel gears 92, a circular gear 93, and a gear plate 94. The transmission shaft 91 is rotatably mounted on the first connecting plate 11. The two bevel gears 92 are respectively mounted on the lead screw 41 and the transmission shaft 91, and are meshed with each other. The circular gear 93 is mounted on the transmission shaft 91. The processing table 1 is provided with a vertical plate 13, and the gear plate 94 is mounted on the vertical plate 13, and is meshed with the circular gear 93.

[0031] It should be noted that the first connecting plate 11 is an L-shaped plate, which supports the pushing component 4 and the transmission component 9.

[0032] In an embodiment of this utility model, when the docking cylinder 3 drives the pushing component 4 to move toward the pneumatic chuck 7, under the meshing constraint of the toothed plate 94, it drives the circular gear 93 and the transmission shaft 91 to rotate, and through the mutual cooperation between the two bevel gears 92, it drives the lead screw 41 to rotate. Therefore, without the need for a drive mechanism, the pin in the docking cylinder 3 can be pushed between the three jaws.

[0033] In one embodiment of this utility model, such as Figure 1 As shown, the grooving assembly 5 includes a second slide module 51, a tool holder 52, and a grooving tool 53. The second slide module 51 is disposed on the processing table 1; the tool holder 52 is mounted on the slide of the second slide module 51; and the grooving tool 53 is mounted on the tool holder 52.

[0034] In an embodiment of this utility model, the grooving cutter 53 and the cutter holder 52 are detachably connected to facilitate the maintenance and replacement of the grooving cutter 53.

[0035] Specifically, when the second slide module 51 is started, it drives the tool holder 52 and the grooving tool 53 to move towards the pin shaft, eventually making the grooving tool 53 fit against the outer wall of the pin shaft. At this time, the rotating drum 2 is driven to rotate, which in turn drives the pin shaft to rotate, thereby cutting a sealing groove on the pin shaft.

[0036] In one embodiment of this utility model, such as Figure 5 As shown, the inside of the rotating drum 2 is provided with a driving component 14, and the output end of the driving component 14 is provided with a feeding plate 15.

[0037] It should be noted that the driving component 14 described in this embodiment can be an electric push rod. After the grooving is completed, the driving component 14 drives the unloading plate 15 to move towards the pneumatic chuck 7 to push out the pin after the grooving is completed, so as to achieve rapid unloading.

[0038] Furthermore, in order to facilitate the collection of the slotted pins, a guide table 16 is provided on the processing table 1. The upper surface of the guide table 16 is inclined to guide the pins into the material trough.

[0039] Specifically, when slotting the pin, the relevant personnel place the pin to be slotted into the material box 8, and the pin slides through the channel into the docking cylinder 3. Then, the relevant technicians start the first slide module 10, which drives the docking cylinder 3 to move towards the pneumatic chuck 7. At the same time, with the cooperation of the transmission component 9, the lead screw 41 rotates, and the ball slider 42 drives the push plate 43 to move towards the pneumatic chuck 7, so as to push the pin in the docking cylinder 3 into the pneumatic chuck 7 until one end of the pin is in contact with the unloading plate 15, thus realizing the automatic feeding of the pin.

[0040] After the material is loaded, the first sliding module 10 drives the docking cylinder 3 to reset. During this process, with the cooperation of the transmission component 9, see [link to relevant documentation]. Figure 4 When the push plate 43 moves to the initial position (the right side of the connection between the material box 8 and the docking cylinder 3), the pin in the channel will automatically fall into the docking cylinder 3.

[0041] Then, the relevant personnel can control the pneumatic chuck 7 to start, so as to center and position the pin on the pneumatic chuck 7. Then, the relevant personnel can control the second slide module 51 to start, driving the tool holder 52 and the grooving tool 53 to feed towards the pin until the grooving tool 53 abuts against the outer wall of the pin.

[0042] At this time, the relevant personnel can control the rotating drum 2 to rotate, and drive the pneumatic chuck 7 and the pin shaft to rotate, so that the grooving cutter 53, which is fed, can cut an annular groove on the outer wall of the pin shaft.

[0043] After grooving is completed, the grooving cutter 53 retracts to its original position and controls the drive unit 14 to start. The drive unit 14 controls the unloading plate 15 to move towards the pneumatic chuck 7 to push out the pin. The pin eventually rolls down along the guide table 16 into the material box.

[0044] In summary, the grooving device for pin processing according to this utility model embodiment ensures the continuity and stability of the processing process by realizing automatic feeding of the pin, thereby significantly improving the overall efficiency of the grooving operation.
